I agree you should get something from exp and its a good idea, but the reward shouldn't be relics imo. The idea of relics doesn't go hand in hand with exp. Even emps wouldn't really be suitable, but maybe if they gave people the chance to buy voiddust with exp and not just conquest points etc? That would mean more VW shouts for more varied VWNM, and increase in EXP parties. Also it would increase the amount of times you could try for the infamous glowing weapons. I think this idea was attempted with making voiddust available from conquest points and the like but hardly anyone parties outside abyssea anymore, especially 75+, so I think this would be a more welcome use for exp.
